Participants were exposed to the ‘Asian disease’ problem (Tversky & Kahneman, 1981). When the problem was subtly framed as a medical decision problem previous findings were replicated: participants avoided the risky option when the problem was framed positively, but preferred the risky option when the problem was framed negatively. This reversal of preferences was eliminated however, when the same problem was subtly introduced as a statistical problem. The results are interpreted as evidence for the impact of context cues on the representation of decision problems. © 1998 John Wiley & Sons, Ltd. 相似文献

Empowerment‐based strategies have become widely used method to address health inequities and promote social change. Few researchers, however, have tested theoretical models of empowerment, including multidimensional, higher‐order models. We test empirically a multidimensional, higher‐order model of psychological empowerment (PE), guided by Zimmerman's conceptual framework including three components of PE: intrapersonal, interactional, and behavioral. We also investigate if PE is associated with positive and negative outcomes among youth. The sample included 367 middle school youth aged 11–16 (M = 12.71; SD = 0.91); 60% female, 32% (n = 117) white youth, 46% (n = 170) African‐American youth, and 22% (n = 80) identifying as mixed race, Asian‐American, Latino, Native American, or other ethnic/racial group; schools reported 61–75% free/reduced lunch students. Our results indicated that each of the latent factors for the three PE components demonstrate a good fit with the data. Our results also indicated that these components loaded on to a higher‐order PE factor (X2 = 32.68; df: 22; p = .07; RMSEA: 0.04; 95% CI: .00, .06; CFI: 0.99). We found that the second‐order PE factor was negatively associated with aggressive behavior and positively associated with prosocial engagement. Our results suggest that empowerment‐focused programs would benefit from incorporating components addressing how youth think about themselves in relation to their social contexts (intrapersonal), understanding social and material resources needed to achieve specific goals (interactional), and actions taken to influence outcomes (behavioral). Our results also suggest that integrating the three components and promoting PE may help increase likelihood of positive behaviors (e.g., prosocial involvement); we did not find an association between PE and aggressive behavior. Implications and future directions for empowerment research are discussed. 相似文献

In a recent article, T. V. Akhutina and L. S. Tsvetkova (1983, Brain and Cognition 2, 129-134) presented an analysis of the Luria-Nebraska Neuropsychological Battery. Along with their generally positive review, they raised questions regarding the importance of the qualitative aspects of patients' performance in the interpretation of the battery. We agree with the authors that any interpretation of the battery which does not consider qualitative performance can limit the power and applicability of the battery. The procedures of item analysis and qualitative analysis are discussed as essential to a comprehensive interpretation of the battery. Also discussed are comments on additional scaling for the battery and the development of a standardized qualitative scoring system. 相似文献

F ranzén , O. On spatial summation in the tactual sense. A psychophysical and neurophysiological study. Scand. 1. Psychol ., 1969, 10, 193–208 .—Individual magnitude estimation scales of apparent intensity of a 300 c/s vibration applied to the volar aspect of the finger-tip as a function of displacement and the number of fingers stimulated were obtained. Spatial summation seems to take place with a lawful increase in perceived intensity as two and three adjacent sensory channels are excited at the same time. Median nerve compound action potentials following electrical stimulation of the index and middle fingers were recorded. A mathematical model is presented to describe and predict spatial summation. The results are interpreted in terms of funneling action of nervous tissue. 相似文献

The theory of signal detectability was applied to vibrotactile sensitivity in two experiments. The first experiment showed The psychometric function to be satisfactorily linear when a sensitivity index of the d family was plotted against the signal intensity expressed in decibels. The second experiment yielded receiver-operating-characteristic (ROC) curves of a familiar form for the yes-no and rating response methods. Reasonably consistent estimates of sensitivity were obtained in the second experiment from the yes-no. rating, and forced-choice methods. The sensitivity indices examined were d’ and de’, based on Gaussian density functions; A, based on Rayleigh density functions; and the distribution-free indices, P(A) and F(C). For each type of index a tendency was observed for the forced-choice value to be lower than the yes-no and rating values. 相似文献
